32、 accordance with ISO 14329.ISO 14273 has been revised to align it with ISO 17677-1.DIN EN ISO 14273:2016-11 EN ISO 14273:2016 (E)5 1 ScopeThis International Standard specifies specimen dimensions and a testing procedure for tensile shear testing of spot and embossed projection welds, in overlapping

33、sheets, in any metallic material of thickness 0,5 mm to 10 mm, where the welds have a maximum diameter of 7t (where t is the sheet thickness in mm).The object of tensile shear testing is to determine the tensile shear force that the test specimen can sustain.2 Normative referencesThe following docum
